To cbZZ whom it may concern:

Be it known that I,WILLIAM J OHN BREWER, a subject of the Queen of GreatBritain, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvements in Vehicles Having Roller-Bearings; and I do herebydeclare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to an improvement in vehicles havingroller-bearings.

The invention may be applied to the ordinary carts or carriages incommon use without especial change. In fact, it may be applied to anyvehicle, and it is especially designed for this purpose. It is obvious,however, that it is not restricted to vehicles, but can be applied toany rotating body.

My invention consists in the construction and combinations of parts, ashereinafter described, and specifically set forth in the claims.

In the accompanying drawings, Figure 1 is a side view of a portion of acart or other vehicle, showing my invention applied thereto. Fig. 2 is arear view of the same. Fig. 3 is a side View similar to Fig. 1, butshowing the spring below the axle. Fig. 4 is a rear View of the cartshown in Fig. 3. Fig. 5 isa crosssection on the line 5 5 of Fig. 6. Fig.6 is a transverse sectional View of my improved roller-bearing. Fig. 7is a similar transverse sectional View of my roller-bearing, but showingthe spacing-thimble and one of the rollers in section. Fig. Sis atransverse sectional view showing a modification. Fig. 9 is a sectionalview through a part of the supportingring, showing how the ends thereofare joined together; and Fig. 10 is a side view of a portion of one ofthe supporting-rings.

a represents the bottom of a carrier or truck, and b shackle-bars,preferably curved, to which the semi-elliptic springs c are attached bythe links d. These springs c are supported in journal-boxes e, which inturn are supported on the axle f. A tie-rod 9 conmeets the twojournal-boxes e, which rod is used to overcome the effect of lateralthrusts, which occur, for example, when the vehicle is traveling withone side lower than the other.

it represents curved bolts nearly U shaped, which are fastened by nutsabove the springs c and passdown and around the journalboxes e. One ofthese bolts runs from side to side and two from end to end of thejournal-boxes 6, thus holding said boxes firmly in contact with thecorresponding springs c. Shorter bolts 2' i run from the journal-boxes 6through or around the springs c and are held by nuts above said springsc. The tops and bottoms of the journal-boxes e are fiattened forengagement with the springs c and bolts h, respectively. The relativearrangement of the journal-boxes e and springs c and the supporting andfastening bolts hand 'i ri. make a compact and almost rigid structure,keeping said springs and journal-boxes firmly together in their relativepositions.

In Figs. 1 and 2 the springs c are shown above the axles, and in Figs. 3and l they are shown below said axles, the latter construction beingespecially valuable when a low wagon or cart is desired.

The journal-boxes e are preferably made in two parts, as shown in Fig.5, which parts are provided with lips 7', connected by bolts 7e,although it is obvious that any other convenient means of making theboxes and fastening them together may be used. One or both of thesehalves maybe provided with a steel wear-ring Z, if desired. The box isof course hollow for the reception of the rollers.

One great advantage ofthis construction is that itmay be applied to theaxle of any cart or wagon without substantial change. For example, itmay be applied to the ordinary square or rectangular axle of a cart, asshown in Fig. 5. The axle as a whole revolves, being supported by therollers in the roller-bearing, and one of the wheels is usually fastenedto the axle, as by meansof the key m, Fig. 2, while the other wheelrevolves freely on said axle, thusmaking it easier to turn corners.

The central part of the journal-box e is provided with blocks a, whichclosely fit around the square axle shown in Fig. 5. \Neanrings 0,provided with flanges 17, closely encircle the blocks 17., and therollers q are supported on one side by these wear-rings 0 and on theother by the wear-rings Z, which are located outside of the rollers q.The rollers q are preferably mounted in pairs upon axles s and aresecured on said axles by pins 15.

WVashers u are preferably used between said are preferably recessed forthe reception of the springs c, and in the construction shown in Fig. 7the walls of this recess extending downward into the journal-box performthe function of the circular projection 17.

The axles .9 may be made round, with an enlarged central portion, asshown in Fig. 6, or round and of the same diameter throughout, as shownin Fig. 7, or with round ends and an enlarged square central portion, asshown in Fig. 8. r

The Wear-rings 0 and Z may be dovetailed into the box to hold them inplace, if necessary.

Plates w, of rolled steel or other suitable material, are interposedbetween the springs c and the boxes 6, and plates .7; and y arepreferably used above the springs 0, through which plates the bolts hand z' pass, thus preventing said bolts from injuriously affecting thesprings. The ends of the journal-boxes e are preferably removable, beingfastened thereto by screws 2. The two halves of the journal-boxes arefastened together at their ends by means of bolts 1, (shown in dottedlines in Fig. 5,) which pass through or into the ends of thejournal-box, thus firmly fastening together the end portions of the twohalves of the journal-box.

The rollers q may be made solid and of any suitable material, or theymay be made in disks, as shown in Fig. 8. By making them in disks, whichmay be left loose upon the axles s or fastened together in any suitableway, the cost of manufacture is considerably reduced.

The numeral 2 in Fig. 7 represents two parallel supporting-rings whichare perforated for the passage of the axles 3. These rings are spacedapart by the thimbles 8, each end of which is provided with a shoulder.

The two rings 2, with the spacing-thimbles and the rollers connectedtogether by their axles, form a complete structure, which may be removedas a whole by slipping out from the journal-box when the same is opened.It is obvious, of course, that the two halves of the journal-box may behinged together instead of bolted, if desired.

One advantage of the construction herein shown is that the end of thejournal-box may gether, as shown in Figs. 9 and 10.

be taken off and any one of the rollers, should it happen to be worn,may be removed and replaced by a new one without taking the wholestructure to pieces. This is a great desideratum from the manufact-urersstandpoint in that it enables repairs to be made very quickly andcheaply.

The rings 2 have their ends fastened to- If desired, each of these ringsmay be made in two parts, and this is the preferable method ofcpnstructing them. In Fig. 9 a block 4 of sufficient size overlaps theadjoining ends of the two halves of the parallel rings 2, and bolts 5pass through the rings in said blocks, holding the half-rings firmlytogether. This is the manner of joining together the paired rings ofFig. 7 and also of the single rings 6. (Shown in Fig. 8.) In said Fig. 8only one supporting-ring 6 is shown, and this is the simplest andcheapest construction to make. This ring 6 is made of halves, as alreadydescribed. Said halves are stamped out, and in the process of stampingsquare holes are made at suitable intervals. The axles 8 (shown in Fig.8) have a squared enlarged central portion which passes through thesquared perforations in the rings 6, and screws 9 pass through saidrings and through said axles, thus uniting the ring 6 firmly with allthe axles s.

I have shown my improved roller-bearing I as applied to a cart; but itis by no means re stricted to such a use. It maybe applied to anyrotating body and is especially applicable to the axle-boxes of railwayand street cars, as the recess in center takes up but little room andthe rollers can be applied to the axle outside of the horn-plates, thusrendering it possible to use the rollerbearings on cars already in usewithout rebuilding the horn-plates. My invention, therefore, is ofespecial value to be applied to axles already constructed and where theconditions are such that little room can be given to the rollenbearings.

It is of course obvious that many changes might be made withoutdeparting from the spirit of my invention, and I wish it to be expresslyunderstood that I do not limit myself to the exact details shown anddescribed.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. The combination with a cartbody, springs carried by said body and theWheels and axles of the cart, of roller-bearings interposed between saidaxles and said springs, each of said roller-bearings comprising ajournal-box provided with a recessed portion in which one of saidsprings is seated, and antifriction-rollers arranged on either side ofand guided by said recessed portion, substantially as described.
